Description
Pouring ring GL 45 red PBT is a heat-resistant laboratory bottle accessory for GL 45 screw threads, intended to support clean, controlled pouring of liquids. Manufactured from polybutylene terephthalate (PBT) in red and specified as resistant up to 180 °C, the ring is positioned between the bottle neck and the closure to form a defined pouring lip that reduces drips during transfer of reagents and media. The PBT construction makes it suitable for applications where elevated temperature resistance beyond standard polypropylene is required, while remaining compatible with common GL 45 laboratory bottles used in chemistry, biology and analytical work. Pack size is 10 pc(s), with a net weight of 0,001 kg per ring, so the accessory adds virtually no mass to the bottle. These pouring rings from manufacturer Witeg combine thermal durability with a practical pouring aid for routine and warmer process conditions. The red colour allows quick visual identification among other thread components. Designed for GL 45 vessels, the ring improves handling and bench cleanliness without compromising the bottle’s primary sealing function in everyday laboratory workflows.

Questions about Pouring rings GL 45
What is this article?
Pouring rings GL 45 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
